| Defence Institute of Advanced Technology(DIAT) has developed “ANANYA” water-based disinfectant spray with nanotechnology assisted formulation. This spray can be used by anyone, from a common man to a healthcare worker, for the individual as well as large scale use. This spray can be used on masks, PPEs, hospital linens, as well as other likely contaminated surfaces such as medical instruments, elevator buttons, doorknobs, corridors and rooms. This formulation adheres very effectively to fabric, plastic and metallic objects, and its toxicity to humans is negligible. The shelf life of the spray is said to be more than 6 months.
